Or rather - Forget the propagators, its not even possible to replace a scalar with something slashed.

a GS[q].GS[l]

%/.a GS[l]->GS[J]

Does not give

GS[q].GS[J]

I really dont understand why it is not possible to replace when the matrices are dotted together.

I would really appreciate it if some has a solution for this problem

Thanks
